IIS and NTI Release New DiskSig Pro Software to Improve Computer Evidence Accuracy.

Business Editors/High-Tech Writers

TEMPE, Ariz.--(BUSINESS WIRE)--June 18, 2003

Integrated Information Systems ("IIS") (OTCBB: IISX), a leading provider of secure integrated information solutions, today announced that IIS recently completed development of DiskSig Pro 3.1, a powerful cross validation tool for proving the accuracy of bit stream backups used in computer forensics. DiskSig Pro 3.1 is owned and marketed by Gresham, Ore.-based New Technologies Inc. ("NTI").

"Civil and criminal attorneys are growing increasingly more experienced in dealing with computer evidence issues," said NTI President Michael R. Anderson. "Attorneys are challenging the expertise of computer forensics specialists and the admissibility of computer-related evidence by accusing computer forensics of being a 'junk science.' IIS developed DiskSig Pro 3.1 with the SHA256 hashing algorithm which has been tested for accuracy by the National Institute of Standards and Technology (NIST). The new DiskSig Pro 3.1 is an outstanding weapon to counteract 'junk science' attacks and ensure the highest level of accuracy in the bit stream backup process. This powerful tool ties perfectly with our recent release of SafeBack, version 3.0, which is used to create 'evidence grade' bit stream backups of computer evidence," he added.

NTI was the first corporation to introduce computer forensics training and software to Fortune 500 corporations and Big 5 accounting firms in 1996. Since that time, NTI has also provided significant support to the U.S. military, U.S. intelligence agencies and law enforcement departments. The FBI, CIA, NSA and IRS are among the nearly 8,000 customers NTI serves in all 50 states and countries throughout the world.

"We are pleased at the high level of value we continue to provide to NTI and their clients. DiskSig represents the next step toward ensuring that NTI remains a valued partner for U.S. military and law enforcement agencies," said Jim Garvey, chairman, chief executive officer and president of IIS. "The IIS team in Portland has done an outstanding job helping NTI in the development of some of its leading-edge technology," he added.
